The idle computers on a local area, campus area, or even wide area network represent a significant computational resource--one that is, however, also unreliable, heterogeneous, an...
In distributed systems, transcoding techniques have been used to customize multimedia objects, utilizing trade-offs between the quality and sizes of these objects to provide diffe...
Queries are widely used for acquiring data distributed in opportunistically formed mobile networks. However, when queries are executed in such dynamic settings, the returned result...
